VSC7321
VSC7321 is 10 x 1 Gigabit Ethernet MAC manufactured by Vitesse Semiconductor.
DESCRIPTION
: Lansing™ is an advanced Ethernet MAC chip, allowing a system with a standard CSIX-64 host interface access to 10 trispeed (10/100/1000 Mbit/s) Ethernet ports. The 10 separate tri-speed MACs support both half-duplex and full duplex at 10/100 Mbit/s and full duplex at 1 Gbit/s. On-chip FIFOs capable of handling short-haul flow control are located between the Ethernet ports and the CSIX-64 interface. These FIFOs are also useful for smoothing bursty traffic on both the CSIX-64 and the Ethernet ports, and for pensating for the bursts generated when aggregating links. Lansing™ can be used together with Meigs-I™ in a flexible port aggregation or port trunking mode. The scheme can be based on MAC addresses or MPLS tags. A prehensive set of statistics...
